Benefits of technology

The present invention allows for better control of a work plant in a single operator control. This means that all the functions that control the position of the plant can be combined into one system.

Problems solved by technology

These differences in control locations and / or different functions result in operator confusion, further resulting in reduced productivity.
Moreover, current skid steer loaders do not incorporate all control functions for positioning an implement within a single operator control, such as a hand control, which could simplify operation of the work vehicle.

Embodiment Construction

[0013]FIG. 1 shows a work vehicle 10 provided with a frame 12 that rotatably carries a plurality of wheels 14. Alternately, a track drive or other appropriate drive system to movably drive the frame may be used. A manipulating structure 16 includes an arrangement of structural members and actuators controllable by an operator (not shown) such as by a second operator control 24, such as a joystick or lever, to manipulate an implement 18 to perform work. As further shown in FIG. 1, second operator control 24 for controlling the work vehicle by certain movements of an operator's right hand with respect to the controls are located within a cab structure 13. Typically, a first operator control 25 associated with an operator's left hand is associated with controlling other operational aspects of the work vehicle such as speed and direction. Frame 12 structurally supports cab structure 13 to surround and protect the operator. A door 20 provides operator ingress / egress to work vehicle 10, i...

Abstract

A work vehicle includes a motor associated with selectable movement of a frame by a first operator control. The frame structurally carries a cab structure and a manipulating structure associated with an implement for performing work. The manipulating structure is selectably movable by a second operator control located in the cab structure. All control functions associated with positioning the implement with respect to three different rotational axes are manipulable using the second operator control.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to the field of work vehicles having implements for performing work. It relates more particularly to implement control of work vehicles.BACKGROUND OF THE INVENTION[0002]Work vehicles, such as a skid steer loader, are increasingly being used on job sites. Skid steer loaders are typically used as general utility machines, due to their versatility and ability to operate on job sites having reduced amounts of surface area.[0003]Despite their versatility, skid steer loaders may be configured differently to control implements, such as a blade or bucket, with which to perform work. That is, the controls may be located in different positions, or perform different functions with respect to the implement, such as raising the arms or rotating the implement about a rotational axis. These differences in control locations and / or different functions result in operator confusion, further resulting in reduced productivity. Moreover,...
